With the increase in the importance of vehicular transportation, the study of contact patch parameters including the contact patch forces and the tire-road friction has become essential from the perspective of improving vehicle safety as well as vehicle performance. The current work aims at analyzing the effect of the nonlinear elastic and nonlinear viscoelastic nature of tire tread rubber by modifying two commonly used rubber friction models (Gim's analytical model and Heinrich-Klüppel (HK) friction model) in order to implement the nonlinear elasticity and the nonlinear viscoelasticity of rubber. Gim’s analytical model is modified by changing the linear elastic constitutive equation used in the original model to a nonlinear elastic equation based on the strain energy density of rubber. Results are obtained for a test simulation using this modified model and an experimental method is proposed to validate the modified model’s force predictions. The HK friction model computes the hysteretic sliding friction coefficient of rubber based on the viscoelastic modulus. It however, does not consider the (experimentally proven) dependence of viscoelastic modulus of rubber on the applied strain amplitude and temperature. The current work thus aims at implementing this dependence and modifying the classical HK friction model. A test simulation run for a rubber block sliding on a rough surface using the modified HK friction model yielded friction results that are sensitive to the input strain amplitude and temperature.
